Abstract

Game of Nines is a game where 2 people bargain with each other to divide 9 points, where they both have a certain minimum necessary value(MNS) they have to achieve. This game is used, since it was first introduced by Kelly et al. (1967), to get a better understanding of the bargaining process. In the study performed by Daamen (2014) a start was made to make a simulation of the human-agent bargaining process. In this study we set out to add a layer of reality to this simulation by adding the ability to call the agent on their lies, asking for a favor and not having to specify your MNS as well as adding another agent which does not change behavior based on the opponent. Results show that these additions make for a simulation where people are more prone to change tactics based on their opponent. They do this by changing the amount they ask for a favor, the amount they use a final offer and the amount they lie about their MNS value.
